JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Europe 2015 - The D3SIGN product range from Porcher Industries offers potential 3D solutions, including a towpreg technology dedicated to automated, advanced fibre placement (AFP) and filament winding.
These innovative products provide potential applications for out-of-autoclave (OOA) processing. These towpregs are continuous carbon or glass fibres treated or impregnated with high-performance thermoplastics. Depending on the final application, the polymer content by weight can range from 30% to 50%. According to customer requirements, the fibres can be fully impregnated in various widths. Compared to slitted tapes, towpregs are 100% continuous, avoiding any splice. With the D3SIGN solution, the industrial process is optimized: high-speed processing, lower energy consumption, low curvature angle, constant weight and width along the towpreg, no dry/lift fibres on the towpreg surface (low pollution of the AFP machine), and less downtime (no splice management). Mechanical properties are also improved: no weakness in the final part (no splice), homogeneous performance (stable fibre content along the towpreg), and management of non-isotropic performance in the final part. Finally, costs are reduced: no carbon waste during the AFP process and more efficient towpreg process (energy, speed, constant weight and width). The D3SIGN towpreg is of particular interest for the aerospace, aeronautics and oil & gas industries.More information: www.porcher-ind.comBooth: P31
